kardiorenalen

Kardiorenale refers to conditions affecting both the heart and the kidneys. It encompasses a spectrum of interconnected diseases where dysfunction in one organ negatively impacts the other. The term is derived from the Greek words "kardia" (heart) and "nephros" (kidney). This relationship is well-established, as the heart and kidneys play crucial roles in maintaining overall circulatory homeostasis. The heart pumps blood throughout the body, including to the kidneys, which filter waste products and regulate fluid balance. When the heart is unable to pump blood effectively, the kidneys may not receive adequate blood flow, leading to reduced function. Conversely, impaired kidney function can lead to fluid retention, increased blood pressure, and electrolyte imbalances, all of which can strain the heart.

The kardiorenale syndrome is often categorized into different types based on the primary organ affected. For example, Type 1 describes a sudden worsening of heart function that leads to kidney injury. Type 2 involves chronic heart dysfunction that leads to progressive kidney disease. Type 3 is characterized by acute kidney injury that precipitates cardiac dysfunction. Type 4 occurs when chronic kidney disease leads to cardiac abnormalities. Type 5 involves systemic conditions affecting both organs, such as sepsis. Management of kardiorenale conditions focuses on addressing the underlying causes and managing the symptoms of both heart and kidney failure. This often involves a multidisciplinary approach with cardiologists and nephrologists working together.
